Application filed January 3l, 1921. Serial No. 441,248.

To all whom t may concern.'

Be it lrnown that I, ,Tor-IN O. Neiman, a citizen ot the United States, residing at Lombard, in the county of Du Page and State of Illinois, have invented. certain new and useful improvements in Fireplaces, ot which the following is a specification.

This invention relates to fireplaces, and has for its object the production of a nreplace that can be very conveniently and etectively installed and that will present a desirable appearance and at the same time will be very efficient. @ther objects of the invention will be apparent from a consideration of the accompanying drawing and the following description thereof.

Fig. 1 of the drawing is a front elevation oi a fireplace embodying the features of my invention; Fig. 2 is a side elevation of the same; and Fig. 3 is a vertical central section of the fireplace and chimney along the line 3-8 of Fig. l.

The central feature of the lirep-lace coinprises an integral casing 5 of cast iron, arranged to enclose the ash pit, the grate, the combustion chamber, and the flue to the chimney, so as to prevent any leakage from these chambers into the walls or into the room, and so as to form a proper support for the mason work and other portions oit the walls oi the fireplace. lt is to be understood, however', that this casing may be built up in any suitable manner, such as by means ott plates of metal, cast or rolled, suitably connected together.

The casing 5 comprises a rear wall (i which extends behind the ash pit 7 the lire-bed chamber 8, and the combustion chamber S, and supports, at its upper end, a iiue 1() through which the burned gases pass 'from the combustion chamber to the chimney. This ilue comprises a horizontal passageway of suitable size positioned near the central upper portion of the casing. The casing also has an upper horizontal plate 11 and a vertical i'ront plate 12, the latter having a wide flange 18 surrounding` the opening 14 which allows a suitable draft for the dre and a suitable openingior removing the ashes from the grate. l

Any suitable grate may be used in the casing, either for wood or coal; and, as the grate is no partof my invention, it has not been illustrated herein. The floor 15 ot the ash pit may be made of any suitable cement or other material. The front Wall 16 in front of the fireplace is supported by the flange 13, and the other walls of the replace are built up in any suitable manner, and all of the walls may be of any suitable material. rlhe chimney flue 17 entends downwardly below the iiue 10, and any suitable arrangement may be provided for cleaning it out in an ordinary manner. A damper 18 may be inserted in the iue 10 in any suitable manner, with a rod 19 for opening and closing the same. f

On the sides of the casing are air spaces 21; in the rear of the casing is an air space 22, and also above the casing is an air space Q3, these air spaces being all connected, and throughout these spaces, when the fire is operating, air circulates by entering through grated openings 9A.- in the lower portion ot the sides and passingl outwardly through the grated openings 25 in the upper portions oi the sides. By these means the air circulating around the casing 5 takes up heat therefrom and is carried into the room and thus prevent-s waste by conduction outwardly through the walls. This also prevents the casing from 'becoming overheated, and hence warped or otherwise injured, and reduces the danger of overheating of the walls and thus sett-ing lire to the building.

In the rear of the air chamber 22 is placed a vertical sheet 26 which very materially reduces the waste heat. The greater portion et the air in) the rear chamber passes upwardly between the sheet 2.6 and the rear wall ot the casing, but a small portion thereoi passes between the sheet 26 and the wall Q7 ot the chimney. inasmuch as ordinary dry air absorbs but little radiant heat energy it will be seen that the sheet 2G will absorb most oiz the radiant energy from the wall 6 land will radiate a large portion thereof back to the wall 6, and thus prevent its passing into the wall 27. At the same time the sheet 26 gives two more surfaces of contact for the air and thus materiallyrassists in heating the air. In this manner the air circulation in the rear passageway is materially increased because of the greater amount of heat which the air can absorb in this passageway-with reference to `the side passageway.

As a consequence the air circulates in the rear, although the inlets and outlets for the air are on the sides, and the side air chambers are much larger than the rear chamber.

Suitable shutters 2S are placed in the air inlets and outlets, so as to reduce the heat ing of the room by the fire when desired.

l' claim as my invention:

1. In a fireplace a casing with a rear Vertical Wall` having an opening in the upper` 2. A fireplace having a casing according to claim l and non-conducting` Walls at the sides and the rear and over said easing, and spaced a material distance therefrom, forming connected air chambers around said casing, Said non-conducting Walls having air openings therethrough. Y

3. In a fireplace a combustion chamber, a chimney, an elongated horizontal conduit connecting the upper end of said chamber with said chimney, a material distance above the lower end of said chimney, an air chainber suiroundingI said conduit, and an air inlet and an air outlet connected with said air ch amber.

el. In a fireplace a combustion chamber, an air chamber partly surrounding said chamber, a plate mounted in said chamber paral icl With the Wall of said combustion chainber, and spaced away from the Walls of both of said chambers, and means for `allowing air to pass into and out of said air chamber.

ln testimony whereof, I here-unto set my hand.
